Application Programming Interface
...
In support of Fedora's role in the preservation stack, this release includes two advances:
...
investigation and documentation around backup and restore strategies for Fedora's datastore. By default, the database that Fedora currently is configured to use is LevelDB [
...
8]. This release includes documentation and recommendations for performing backup and restore of the internal data Fedora uses in maintaining state.

External Services
One of the exciting capabilities that Fedora enables is the creation of distributed, asynchronous, message-driven services that are external to the core repository but are triggered by repository events. This release includes an update to the Fedora-related Apache Camel-based [10] toolbox introducing the ability to configure the LDP 'Prefer' header that is used when requesting RDF to be indexed in an external triplestore.

Following the initial implementation of the Web Access Control [119] authorization module, this release furthers that effort with several fixes and improvements. Enhancements include:
WebACLs can now apply to binary resources
An HTTP header, 'On-Behalf-Of', can optionally be configured to offer delegated authorization (documentation [1210])
- A WebACL can be placed on the server acting as the final backstop for authorization decisions for resources that have no other effective WebACL (documentation [1311])
- WebACLs can now include references to 'agentClass' Fedora resources as defined in the Web Access Control specification (documentation [1412])
- An HTTP 'Link' header is included in responses to protected resources pointing to the effective WebACL
Additional documentation of Fedora's implementation of Web Access Controls is available on the wiki [1513].
